Flonase Allergy Relief is the first and only over-the-counter nasal spray intended for relief of all nasal and eye-related allergy symptoms, including runny nose, sneezing, itchy nose, nasal congestion, and itchy and watery eyes, according to a company news release Thursday.

An estimated 50 million people in the United States have nasal allergies, often leading to fatigue, trouble sleeping , learning and attention problems, and performance trouble at work or school, the company said.

The active ingredient in Flonase Allergy Relief, fluticasone propionate, was approved as a prescription medicine in 1994.

The nasal spray will be available over the counter in early 2015, according to GlaxoSmithKline.
